摘　　要：安塞油田化子坪区长2油藏在实施产出水回注过程中,出现水井油压快速长升、各种增注措施有效期短的现象,严重影响注采平衡。通过对高压形成机理的认识,研制出适用的注水减阻剂,并在现场应用,取得了良好的效果。The water re-injection in the implementation process in Huaziping Chang No.2 oilfeild in Ansai resulted the emergence of rapid long-liter oil wells and short period of avaliable work,which seriously affects the balanced injection.Based on the understanding of the formation mechanism of high pressure and water injection development for DRA,it achieves good results in the application of RDA.
